M _BH versus M _* for the VIPERS sample of AGN dwarf galaxies at z < 1 of Mezcua et al. (2023; blue squares), the new “cosmic noon” sample of AGN in low-mass galaxies reported here (red squares), and a compilation of JWST AGN in low-mass galaxies at z > 4 (purple squares). We also show for comparison the low-z AGN of Reines & Volonteri (2015; RV2015; blue dots) and the intermediate-z AGN of Suh et al. (2020; Suh+2020; red dots), whose masses have been computed using the same procedure and parameters as the VIPERS samples. The solid black line shows the local + intermediate-z M _BH–M _* correlation found for the combination of the RV2015 and Suh+2020 samples with a 1σ scatter of 0.5 dex. The red dashed line shows the high-z M _BH–M _* correlation found by Pacucci et al. (2023) for AGN found at z > 4 by JWST based on the detection of broad Hα or Hβ emission. The green dashed–dotted line shows the Shankar et al. (2016) local correlation for inactive galaxies.
